microburst winds to 50 mph or greater, light rainfall, and
isolated dry lightning. The dry lightning means new wildfire
starts will be possible.

degrees of cooling from today`s scorching heat. Scattered showers
and thunderstorms will develop in the afternoon and evening,

rainfall.

Significant heat relief will occur for Tuesday and Wednesday, with
temperatures falling to a few degrees below normal by Wednesday.
Shower and storm coverage and intensity will increase both days, with
a couple of the stronger storms producing locally heavy rainfall.
The chance of storms will linger through the latter half of this
week, although the threat for any severe weather will be low most
days.

...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 9 PM MDT THIS
EVENING FOR THUNDERSTORMS WITH DRY LIGHTNING FOR THE MOUNTAINS,
FOOTHILLS, AND EASTERN LARIMER COUNTY...

The National Weather Service in Denver has issued a Red Flag
Warning for thunderstorms, which is in effect from noon today to
9 PM MDT this evening. The Fire Weather Watch is no longer in
effect.

* Affected Area...Fire Weather Zones 211, 212, 213, 214, 215,
  216, 217, 218 and 238.

* Timing...12 PM to 9 PM MDT Sunday.

* Winds...Gusty winds up to 45 mph near showers and storms.

* Relative Humidity...As low as 13 percent.

* Impacts...Conditions will be favorable for lightning-induced
  ignitions from mostly dry thunderstorms. Locally erratic
  outflow winds near thunderstorms could promote rapid wildfire
  spread in the event of a new start. If a fire were to become
  established, conditions could be favorable for large vertical
  plume growth.

* Thunderstorms...Isolated to scattered (15-25% coverage) of
  mostly dry thunderstorms is expected Sunday afternoon,
  potentially extending into early evening. Thunderstorms will
  be high-based, producing little, if any, precipitation, and
  thus resulting in an increased threat of lightning-induced
  ignitions.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either occurring now....or will shortly. A combination of
strong winds...low relative humidity...and warm temperatures can
contribute to extreme fire behavior.
